I don't think it has much to do with politicians. It has to do with currency counterparties and economic value created therein. Hence my desire to study where I think MMT can make the biggest net impact. Which is likely in currency issuers who are Too Big To Default™.

All money is just an agreed upon fiction by multiple counterparties, and when there's a lot invested in that fiction it becomes fairly undesirable to be the one(s) to pierce the suspension of disbelief.
